Microstructural scale in additively manufactured titanium alloys can vary drastically between different alloys and build processes. Varying thermal conditions during solidification and thermal cycling can refine or coarsen as-solidified microstructures, influencing the final microstructural condition. Cooling rates experienced in the solid state may also impact the scale and morphology of as-transformed microstructures, leading to challenges in controlling microstructural development in the as-built condition. A greater understanding of these phenomenon is required in relation to processing parameters and local conditions to advance microstructural control in metallic alloy additive manufacturing of titanium alloys. This work highlights recent efforts in understanding how thermal conditions and phase transformations influence microstructural scale, and how these insights can be used to tailor titanium builds with additive manufacturing.
